How Autonomous Vehicles May Influence Vertical Curves, At-Grade Railroad Crossings, and Ramp Terminals

This paper builds on the author’s 2017 work on how connected vehicles/autonomous vehicles (CV/AV) may impact the geometric design of roads. The previous work explored the potential modifications to stopping sight distance and provided some thoughts on the potential impacts to lane and shoulder widths, roadside modifications, intersections, and parking. How these differences between the human driver and the expected performance of fully automated vehicles may impact the design of roads are further explored in this paper, with attention on vertical curves, at-grade rail crossings, and ramp terminals. Three situations are considered: AV-only roads, AV-separated roads, and mixed-use roads (AV and human-driven vehicles in the same vehicle stream).
